Development of a Two-Dimensional Resonator Design Tool

One of the engineering challenges in high-field MRI is to have a homogeneous distribution of the RF magnetic field inside human tissue. In this project we develop a design tool for a HEM wrist applicator that has the ability to generate a homogeneous magnetic field inside human wrist. By taking into account the dominant RF scattering effects...

Homogeneous RF Field Distribution Optimization in 3T Abdominal Imaging

The appearance of severe signal drop-outs in abdominal Magnetic Resonance Imaging at 3 Tesla arises primarily from areas of very low magnetic flux density B1 of the transmit field in the body, and is problematic in both obese as well as very thin subjects. In this study, we show how thin patient-friendly pads containing new high permittivity...
